vampirchik [111]

Answer:

The value of test statistic

|Z| = |-2.2883| = 2.2883

Step-by-step explanation:

Step(i):-

Given that the mean of the Population = 57.7miles/gallon

The standard deviation of the Population = 1.9

The mean of sample x⁻ = 57.4

Given that the sample size 'n' =210

level of significance = 0.1

Step(ii):-

Test statistic

$Z = \frac{x^{-}-mean }{\frac{S.D}{\sqrt{n} } }$

$Z = \frac{57.4-57.7}{\frac{1.9}{\sqrt{210} } }$

Z = -2.2883

|Z| = |-2.2883| = 2.2883

Final answer:-

The value of test statistic

|Z| = 2.2883

Arrange the equations in the correct sequence to find the inverse of F(x)=Y=3x/8+x

Brilliant_brown [7]

F(x) = 3x/(8+x) = y

f^(-1) is the inverse function. As its name suggests if f(x) = y that we need to find a g(x) such that g(y) = x

In order to find f^(-1) switch x with y and solve for y

3y/(8+y) = x
x(8+y) = 3y
8x+xy = 3y
8x=3y-xy
8x = y(3-x)
y = 8x/(3-x)

f^(-1) = y = 8x/(3-x)
